Danger, syllogism alert!

Nobody is questioning that raw files are unprocessed - that is exactly what
I wrote. But that does not mean that TIF files are unprocessed, and your
references to the Olympus manuals do not make that point. The same point is
made on p 72 of the E-330 manual, p 64 of the E-5 manual, alluded to on p 79
pf the E-1 manual and so on. The E-1 manual also clarifies TIFF as follows
(p 178, in the Glossary of Terms, and it appears in other manuals too):
" TIFF (Tagged Image File Format) A format used for saving highly detailed
black and white or color image data. TIFF image files can be handled by
software programs for scanners and graphics applications. Non-compressed
image data are stored in this format with this camera."

Notice 'non-compressed' - NOT non-processed - perhaps this is the root of
the confusion. JPEG are processed and compressed, whereas TIFF are not
compressed ... but they most certainly are processed.

     Which is why I'm going to do the comparison as post-processing TIF
files can be done with any graphics software, whereas ORF (Olympus RAW
Format) cannot.  The remark about RAW files being unprocessed is right in
the E-500 manual on page 180, E-510 manual on pages 45 and 109, and in the
E-520 manual on page 135.
